256 NOTES ON CAMBRIDGESHIRE PLANTS. 



and quite unproductive. In Dist. 6 I have looked for this at Mepal 

 and repeatedly at Eoswell Pits, Ely, but always in vain. Mr. 

 Bennett informed me that he had a specimen gathered some years 

 ago by Mr. Fryer in the Chatteris district ; but in what I (rightly) 

 believed to be the spot there was no trace of the plant in 1895, and 

 I find in Herb. Brit. Mus. a specimen labelled "Pits by Vermuy- 

 den's Drain at Horseway, now destroyed, Sept. 17, 1879, A. Fryer." 

 — T. Scorodonia L. My search for this at Gamlingay was un- 

 successful ; it may still occur in White Wood. Beyond Henslow's 

 specimen nothing seems to be known about the Ely record.

Mercurialis jjerennis L. 1. Borley Wood; lane below "The 

 Eivey," Linton. Not recorded from the northern half of the county. 



Farietaria officinalis L. 5. Burwell Church, 1893 ; 1. H. Burkill. 



Salix triandra L. 3. By the Bourn Brook at Toft. 6.* By 

 ditches a little S. of Burwell. — S. aurita L. 2. Dernford Fen. 



Fopulus tremidus L. 3. Fine in Gamlingay Wood. 



Ceratophyllum demersum L. 1. Coe Fen, and 3, in the river at 

 Sheep's Green, Cambridge. 6.'^' Eoswell Pits, Ely. 



Juniperus communis L. 1. Sparingly on the Fleam Dyke. 



Hydrocharis Morsus-RancB L. 3. Sheep's Green, Cambridge. 



[Stratiotes aloides L. was introduced from the Botanical Gardens 

 into a pond on Sheep's Green, Cambridge, where it has driven out 

 the other aquatic plants.] 



Liparis Loeselii Eich. was seen in two localities in Dist. 5 in 

 1896 ; in one I saw fine fruiting specimens. 



Neottia Nidus-Avis Eich. 3."^ Kingston Wood, 1894. 



Ceplialanthera pallens Eich. 1. I have seen fine specimens of 

 this, gathered by Mr. Shrubbs from a wood on the Gogmagogs. 

 This station is quite distinct from that in which Mr. Clarke found 

 the plant in 1859. 5. Mr. Bennett informs me that there is a 

 specimen of this in Hailstone's herbarium at the York Philosophical 

 Society which was gathered in Wanton's station in 1845. 



Ep)ipactis latifolia All. 3.''^ Kingston Wood, 1894 {teste A. Ben- 

 nett). This is not recorded for Cambs in the Flora. Babington 

 says that the Kingston Wood plant is E. media Fr. ; I have found 

 there two plants of what I take to be that species, but the plant 

 frequent in the wood is certainly true E. latifolia. — E, media Fr.
